Wood stove permits in Nashua.
File a mechanical permit with Building Safety.
Inside Nashua, permits come from the Department of Building Safety on the second floor of City Hall, 229 Main Street (603-589-3080, permits@nashuanh.gov). Its residential mechanical application has separate lines for a gas or wood factory fireplace, insert or pellet stove with associated chimney, and for a manufactured chimney or chimney liner, and adds a surcharge when work starts before a permit is issued. The department says every permit application needs a Building and Landuse Application plus one paper and one electronic plan set. Ask which line covers a freestanding wood stove. Hudson, Merrimack and Hollis have their own building departments.
Nashua residential mechanical application/permit (PDF, May 2021)In the historic district, the HDC acts on the building permit.
Nashua’s Historic District Commission, set up in 1980, reviews and acts on all building permit applications for properties inside the city’s historic district, looking at exterior features and how a project relates to its surroundings. Its page lists structural changes to a roof among items to address, while re-roofing on the same roof plane needs no approval. A new chimney or roof penetration is worth raising early. The Commission meets the fourth Monday of each month; questions go to the Zoning Official at 603-589-3090.
Nashua Historic District CommissionBook the concealment inspection before closing walls.
The inspection list on Nashua’s mechanical permit card says wood stoves, pellet stoves and factory-built fireplaces must be inspected before any vent pipe, chimney or fireplace is concealed and again at completion. Metal chimneys also need an inspection before concealment. You must call 603-589-3080 at least a day ahead, and the permit card has to be posted where it is visible from the street.
Nashua residential mechanical application/permit (PDF, May 2021)Nashua now enforces the 2021 code editions.
Nashua’s Department of Building Safety says a 2024 state law updated the New Hampshire State Building Code to the 2021 editions, in effect since December 31, 2024, with New Hampshire amendments posted by the state Building Code Review Board. The department invites questions about which codes apply to a project. Ask your installer to confirm the stove’s clearances and venting against the current edition, not an older manual.

Nashua wood stove installation FAQs.
Which Nashua permit covers a wood stove?
The Department of Building Safety’s residential mechanical application has a line for a gas or wood factory fireplace, insert or pellet stove and associated chimney, and a separate line for a manufactured chimney or liner. It does not name a freestanding wood stove, so call 603-589-3080 or email permits@nashuanh.gov to confirm which applies.
What inspections should I expect?
The permit card says wood stoves, pellet stoves and factory-built fireplaces are inspected before any vent pipe, chimney or fireplace is concealed and again at completion. Call 603-589-3080 at least one day before each inspection, and post the permit card where it can be seen from the street.
Is Nashua handled like Manchester?
No. Nashua uses a mechanical permit filed with its Department of Building Safety at 229 Main Street, with its own inspection list and a separate Historic District Commission. Hudson, Merrimack, Hollis and other neighbouring towns have their own building departments too, so confirm the municipality for your property before applying.
